    ZGGM8.5488 - USA Standard Gear Ring and Pinion Gear Sets is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from Didn't last long even after breaking in as noted Bought them about 3 weeks ago. Set them up ran a pattern and it came out excellent. I broke them in as suggested. I drove it for 15 minutes then let them cool down right after installed. Then drove it very carefully for 500 miles! Which is very hard to do by the way. But I completed the whole 500 miles. I started to notice a little whine I thought maybe its just my truck then it got louder and louder. Tore the rearend apart none of the teeth were missing on the ring gear or the pinion. Ran a pattern about 20 times shimming the pinion and the whole carrier each time! Ran the same pattern every time. It was only hitting on the very end of the toe. Turns out the pinion wore down or was softer on that one side and it had wore it back so that it would only hit the ring gear in one spot! This is after 3 weeks!!!!!! Maybe just bad steel I would think but I won't buy these gears again due to that.
